I propose sometimes to bleach this stock, as with other kinds; but for ordinary purposes I use it in its natural state, without boiling or other preparation, which has*beerr'tbund-"neeessary-ig-usirrgstrawand like materials of which paper has been heretofore made. If the green materials have dried they are steeped before use.
